OBJECTIVE To comprehensively evaluate the quality of adverse drug reaction （ADR） reports in clinical departments or ward （hereinafter referred to as “department”） based on game theory combinatorial weighting-technique for order preference by similarity to ideal solution （TOPSIS）-rank-sum ratio （RSR） method， providing a reference for the further standardization of ADR reporting. METHODS Based on relevant documents and scoring criteria， the ADR report quality evaluation standards previously developed by our team were modified. Using game theory principles， the fusion of subjective and objective weights for each indicator was determined. A game theory combinatorial weighting-TOPSIS-RSR model was developed to evaluate and categorize the quality of raw ADR reports submitted by departments to the pharmacy department at Bozhou Hospital of Anhui Medical University. RESULTS A total of 222 ADR reports from 23 departments were included. The game theory combinatorial weighting method identifies weak points in management， such as ADR symptoms and signs， the description of underlying diseases， timing of ADR， by optimizing the weightings of the indicators. The TOPSIS-RSR method calculates that the mean relative closeness of the departments was 0.401 7， indicating that the overall report quality ranged from moderate to substandard. 20095） Three departments， including neurosurgery， demonstrated medium reporting quality [estinate closeness （Ĉ）i ≥0.506]， while two departments， such as the respiratory department，were rated as unqualified （Ĉi＜0.278）. The remaining departments were all deemed qualified （0.278≤ Ĉi＜0.506）. CONCLUSIONS The developed game theory combinatorial weighting-TOPSIS-RSR method provides an effective approach for the quality evaluation of ADR reports， which not only balances subjective and objective weights but also facilitates comparisons among different departments. There is still room for improvement in the ADR report quality at the hospital.

Gastric cancer with peritoneal metastasis (GCPM) is a common and lethal manifestation of advanced gastric cancer, with a median survival of only 5-11 months. This consensus was developed by 30 experts from Asia (China, Japan, Korea, and Singapore) using the Delphi method and the GRADE evidence grading system. A total of 29 statements were formulated, covering the diagnosis and assessment of GCPM, indications for laparoscopic exploration and NIPS (normothermic intraperitoneal and systemic treatment), treatment regimens, prevention and management of complications, criteria for conversion surgery, and postoperative intraperitoneal therapy. The consensus aims to standardize clinical practice and improve the prognosis of patients with GCPM.

Objective To explore the expression level of visceral adipose tissue-derived serine protease inhibitor(Vaspin)and secreted frizzled-related protein5(SFRP5)in the serum of children with idiopathic short stature(ISS)and its diagnostic value.Methods 70 children with ISS diagnosed in the First Hospital of Zhangjiakou from December 2021 to February 2023 were selected as the disease group,while 72 healthy volunteer children who underwent physical examination were collected as the control group.Immunoluminescence was applied to detect the expression level of VASPIN,Enzyme-linked immunosorbent assay(ELISA)was applied to detect the expression level of SFRP5 the clinical data of children in two groups were analyzed.Receiver operating characteristic(ROC)curve was applied to analyze the diagnostic value of serum Vaspin and SFRP5 for ISS,multivariate Logistic regression was used to analyze the influencing factors of ISS.Results Compared with the control group,the serum Vaspin level in the disease group was obviously increased(2.89±0.92 ng/ml vs 1.81±0.42 ng/ml),while the SFRP5 level was obviously reduced(10.22±2.84 pg/ml vs 13.21±3.53 pg/ml),the differences were statistically significant(t=9.040,5.552,all P＜0.05).The weight,height,body mass index(BMI)and proportion of sexual development stage II～V of children in the disease group were obviously lower than those in the control group,and the differences were statistically significant(t=7.687,6.330,5.559,7.024,all P＜0.05).The area under ROC curve showed that the AUC of Vaspin and SFRP5 and their combined detection in the diagnosis of ISS were 0.768,0.849 and 0.925,respectively,the combined diagnosis efficacy of Vaspin and SFRP5 was better than that of serum Vaspin and SFRP5 alone(Z =3.829,P＜0.001;Z =2.141,P=0.032).Multivariate Logistic regression analysis showed that BMI(OR=0.508,95%CI:0.260～0.991),Vaspin(OR=3.458,95%CI:1.125～10.631)and SFRP5(OR=0.378,95%CI:0.153～0.935)were the influencing factors for ISS(all P＜0.05).Conclusion The expression level of Vaspin in the serum of children with ISS is obviously increased,while the expression level of SFRP5 is obviously reduced.The two are influencing factors of ISS,and the combined detection of their expression levels has certain value in the diagnosis of ISS.

Objective:To evaluate the short-term efficacy and safety of 3D printing patient-matched artificial vertebral body in clinical research and application.Methods:A total of 12 patients with spinal tumors were enrolled 7 males (58.33%) and 5 females (41.67%), aged from 18 to 65 years old in The First Affiliated Hospital of Air Force military Medical University (hereinafter referred to as Xijing Hospital) and Peking University people's Hospital from September 2021 to July 2022. The spinal vertebra defect were restored by using 3D printing patient-matched artificial vertebral body after tumor resection. All patients who accepted TES and 3D printing patient-matched artificial vertebral body implantation were included according to the inclusion and exclusion criteria. The bone interface fusion was evaluated by the imaging fusion criteria of Brantigan and Steffee at 3 and 6 months after operation, the curative effect was evaluated by comparing Japanese Orthopaedic Association (JOA) score at 3 and 6 months after operation, visual analogue scale (VAS) 3 months after operation and intervertebral height at 3 and 6 months after operation with those before operation, and the safety was evaluated by adverse event recording.Results:All 12 patients completed the operation successfully, and the operation sites were thoracic vertebrae in 6 cases (50%), thoracolumbar in 3 cases (25%) and lumbar vertebrae in 3 cases (25%). All patients were followed up. The mean follow-up time was 23.92±3.23 months (range, 19-29 months). No tumor recurrence or metastasis was observed during this period. All patients were followed up at 15 days, 3 months and 6 months after operation. During the 6-month follow-up, X ray results showed that interface of bone and the vertebral body were fused in all of the 12 patients, and the effective rate of fusion was 100%. The 95% confidence interval is calculated to be (75.6%-100%). Six months after operation, the improvement rate of JOA score was excellent in 10 cases, good in 1 case, poor in 1 case, and the excellent and good rate was 91.66%. The preoperative VAS score was 4.08 ±2.47, and during the 3-month follow-up, the VAS score was improved to 1.83 ±1.59. Compared with the preoperative VAS score, the difference was statistically significant ( t=2.635, P=0.023). The intervertebral height before operation, 15 days after operation, 3 months after operation and 6 months after operation were 32.75 (25.94, 68.20), 41.09 (30.55, 70.20), 40.70 (30.23, 67.83) and 40.74 (30.23, 67.08), respectively, and there was no statistically significant difference (χ 2=0.768, P=0.857). No implant-related adverse events occurred after operation. Conclusion:The 3D printing patient-matched artificial vertebral body used in this study has satisfactory short-term efficacy and safety in the reconstruction of spinal stability after spinal tumor resection.

Neuroinflammation mediated by microglia is essential for the occurrence and development of Alzheimer’s disease (AD). Through the analysis of the GEO database, it was found that IL-27 expression decreased in both the cerebral cortex and hippocampus of AD patients. In this study, the AD cell model of BV-2 cells injured by Aβ1-42, the inflammatory cell model of BV-2 cells damaged by LPS, and the inflammatory animal model were established and the effects of IL-27 after its administration in the above models in regulating microglial phenotype and neuroinflammation were evaluated. In the animal models, the number of Iba1+ microglia in the hippocampus was detected by immunohistochemistry, the expression of pro-inflammatory factors such as TNF-α, IL-1β and IL-6 was detected by qPCR, ELISA and Western blot, and the expression of M1/M2 phenotypic markers in microglia was detected by qPCR. To further explore the action mechanism of IL-27, Western blot was used to detect the expression levels of NF-κB, p-NF-κB, IκBα and p-IκBα in microglia after administration of IL-27 and Aβ1-42. The results showed that IL-27 alleviated the abnormal activation of microglia induced by lipopolysaccharide (LPS), decreased the expression of pro-inflammatory factors such as TNF- α, IL-1β and IL-6, transformed microglia induced by LPS or Aβ1-42 from neurotoxic M1 to neuroprotective M2, and improved the abnormal phosphorylation of NF-κB and IκBα induced by Aβ1-42. The research suggested that IL-27 can regulate the M1/M2 polarization of microglia induced by Aβ1-42 or LPS, and alleviate neuroinflammation.

Objective To investigate the relationship between the therapeutic effect of anti-vascular endothelial growth factor(VEGF)and cytokines in aqueous humor in patients with diabetic retinopathy(DR).Methods From July 2023 to December 2023,50 DR patients(56 eyes)who were treated with anti-VEGF drugs in the Department of Ophthal-mology,the Third Affiliated Hospital of Xinxiang Medical University were included in this study.The patients were divided into the diabetic macular edema(DME)group(30 patients,36 eyes)and the proliferative DR(PDR)group(20 patients,20 eyes).Patients in the DME group received an intravitreal injection of aflibercept once a month for three consecutive times,with aqueous humor extracted before each injection.Patients in the PDR group received an intravitreal injection of aflibercept one week before vitrectomy,with aqueous humor extracted before injection and during vitrectomy,respective-ly.The concentrations of vascular endothelial growth factor A(VEGF-A),placental growth factor(PLGF),interleukin(IL)-1β,IL-23,IL-17A,and tumor necrosis factor-α(TNF-α)in the aqueous humor were detected using the Luminex as-say.Before injection therapy,all patients underwent best corrected visual acuity(BCVA)and central macular thickness(CMT)examinations,and their correlations with cytokine concentrations in DR patients before injection therapy were ana-lyzed.Results Compared to before injection therapy,the concentrations of VEGF-A,PLGF,and IL-23 in the aqueous humor of patients in the DME group decreased significantly after treatment(all P＜0.05);additionally,the CMT de-creased,and the BCVA increased(both P＜0.05).After injection therapy,the concentrations of VEGF,PLGF,IL-1β,IL-23,IL-17A,and TNF-α in the aqueous humor of patients in the PDR group significantly decreased compared to before injec-tion therapy(all P＜0.05).Before injection therapy,the levels of VEGF-A,PLGF,and IL-23 in the aqueous humor of pa-tients in the DME group were higher than those in the PDR group,and the differences were statistically significant(all P＜0.05).The correlation analysis results showed that before injection therapy,VEGF was negatively correlated with BCVA(r=-0.767,P=0.004)and was positively correlated with CMT(r=0.662,P=0.019)and IL-23(r=0.765,P=0.004)in the DME group.There was no correlation between the cytokines in the aqueous humor of patients in the PDR group be-fore injection therapy(all P＞0.05).Conclusion Changes in the concentration of VEGF-A,PLGF,and IL-23 are closely related to the occurrence and development of DR.Anti-VEGF treatment can improve BCVA and decrease CMT in DME pa-tients.The expression level of IL-23 in aqueous humor can serve as a predictive factor for the anti-VEGF efficacy in DR pa-tients,providing new targets for early diagnosis and treatment of DR.

Pseudorabies virus(PRV)is the etiological agent of pseudorabies in pigs,which is char-acterized by dyspnea,reproductive disorders,and neurological diseases,and it spreads widely a-round the world.Since 2011,the newly emerged PRV variants have resulted in poor immunity pro-tection of traditional vaccine strains,and the original method of vaccine strain preparation is time-consuming and labor-intensive.Therefore,it is urgently needed to develop an efficient screening method of the vaccine strain at present.Using CRISPR/Cas9 gene editing technology in this study,two single guide RNAs(sgRNA)were designed targeting the virulence gene TK of PRV variant strain CH/JX/2016,and then the enhanced green fluorescent protein the reporter(EGFP)gene was inserted at the TK locus by a homologous repair plasmid.After multiple rounds of plaque puri-fication,the rPRV-ΔTK/EGFP strain was obtained.The results showed the cleavage efficiency of the two sgRNAs was extremely high.The preparation of rPRV-ΔTK/EGFP strain was succeed af-ter only three rounds of purification,and the EGFP expressed normally.The CRISPR/Cas9 system can edit the PRV gene simply,rapidly,and efficiently,and exhibits great potential in the construction of vaccine candidate strains.Meanwhile,the rescued rPRV-ΔTK/EGFP strain not only could be used as a tracer strain in PRV variant infection progresses,but also for subsequent antivi-ral drug screening.

Objective:To investigate the predictive value of left ventricular global longitudinal peak strain (GLPS) for the prognosis of septic patients.Methods:A prospective cohort study was conducted. Patients diagnosed with sepsis and admitted to the intensive care unit (ICU) of the First Affiliated Hospital, Sun Yat-sen University from December 2018 to November 2019 were enrolled. The patient characteristics, cardiac ultrasound parameters [left ventricular ejection fraction (LVEF), right ventricular ejection fraction (RVEF), four-dimensional ejection fraction (4DEF), GLPS] and cardiac biomarkers [N-terminal pro-brain natriuretic peptide (NT-proBNP), cardiac troponin T (cTnT)] within 24 hours of ICU admission, organ support therapies, severity of illness, and prognostic indicators were documented. The differences in clinical parameters between patients with varying outcomes during ICU hospitalization were assessed. Pearson correlation analysis was employed to explore the correlation between GLPS and other cardiac systolic parameters, as well as the associations between various cardiac systolic parameters and sequential organ failure assessment (SOFA) score. Receiver operator characteristic curve (ROC curve) was drawn to analyze the predictive capacity of cardiac ultrasound parameters and cardiac biomarkers for death during ICU hospitalization in septic patients.Results:A total of 50 septic patients were enrolled, with 40 surviving and 10 dying during ICU hospitalization, resulting in a mortality of 20.0%. All patients in the death group were male. Compared with the survival group, the patients in the death group were older, had a higher prevalence of diabetes mellitus, and received continuous renal replacement therapy (CRRT) more frequently, additionally, they exhibited more severe illness and had longer length of ICU stay. The levels of GLPS and cTnT in the death group were significantly elevated as compared with the survival group [GLPS: -7.1% (-8.5%, -7.0%) vs. -12.1% (-15.5%, -10.4%), cTnT (μg/L): 0.07 (0.05, 0.08) vs. 0.03 (0.02, 0.13), both P < 0.05]. However, no statistically significant difference was found in other cardiac ultrasound parameters or cardiac biomarkers between the two groups. Pearson correlation analysis revealed a negative correlation between GLPS and LVEF ( r = -0.377, P = 0.014) and 4DEF ( r = -0.697, P = 0.000), while no correlation was found with RVEF ( r = -0.451, P = 0.069). GLPS demonstrated a positive correlation with SOFA score ( r = 0.306, P = 0.033), while LVEF ( r = 0.112, P = 0.481), RVEF ( r = -0.134, P = 0.595), and 4DEF ( r = -0.251, P = 0.259) showed no significant correlation with SOFA score. ROC curve analysis indicated that the area under the ROC curve (AUC) of GLPS for predicting death during ICU hospitalization in septic patients was higher than other cardiac systolic parameters, including LVEF, RVEF, and 4DEF, as well as cardiac biomarkers NT-proBNP and cTnT (0.737 vs. 0.628, 0.556, 0.659, 0.580 and 0.724). With an optimal cut-off value of -14.9% for GLPS, the sensitivity and negative predictive value reached to 100%. Conclusion:GLPS < -14.9% within 24 hours of ICU admission in septic patients indicated a reduced risk of death risk during ICU hospitalization, while also correlating with the severity of organ dysfunction in this patient population.

Objective:To describe disability rates of dementia in community residents aged 65 years and over in China,and explore related risk factors of disability.Methods:This study conducted an in-depth data analysis of the China Mental Health Survey.World Health Organization Disability Assessment Schedule 2.0(WHODAS 2.0)was used to assess dementia disability,Community Screening Interview for Dementia(CSID)and Geriatric Mental Status Examination(GMS)were used for dementia screening and diagnosing.Univariate analysis was used to calcu-late the weighted disability rates of dementia in population and in patients,and their population distribution.Multiple linear regression and logistic regression were used to analyze the risk factors of the occurrence of dementia disability and its severity.Results:The weighted disability rate of dementia was 2.1％in population,and 38.6％in pa-tients.The disability rates of comorbid dementia in population and in patients were higher than those of patients with only dementia.Female,older age,lower education level,lower economic status,and lower cognitive test scores in CSID had higher disability rates of dementia in population.Female and urban resident had higher disability rates of dementia in patients.Multiple linear regression showed economic status(β=0.11),gender(β=0.11),age(β=0.10),and treatment in the last 12 months(β=-0.20)were statistically associated with WHODAS 2.0 scores.Multiple logistic regression showed female(OR=2.81)and treatment in the last 12 months(OR=2.38)were statistically associated with disability.Conclusions:Persons with low economic status,female and elderly peo-ple are the high-risk groups for dementia disability.It should be paid attention to prevent dementia and its conse-quential disabilities.
